Key Applications:
EPDM: Water systems, outdoor seals
PE: Low-cost chemical liners
Silicone: Food/medical, high-temp seals
PTFE: Corrosive chemicals, semiconductors
FKM: Automotive fuel systems
FFKM: Extreme chem/temp (aerospace, oil & gas)
NBR: Petroleum, hydraulic systems
Unique Advantages:
EPDM: Best weathering resistance
Silicone: Widest temp range (flexibility maintained at extremes)
PTFE: Most chemically inert
FFKM: Combines PTFE’s chemical resistance with rubber elasticity
